To all whom it may concern:

Be it known that I, WILLIAM F. HENDER- soN, a citizen vof the United States, residing at Pittsburgh, in the count of Allegheny and State of Pennsylvania, ave invented a newv and useful Improvement in Stuifer Horns, of which the following is a specification. v

This invention relates particularly to stufi'er-horns for sausage machines.

As it is well-known in the art, it is common, in stufing a tube, or casing, in preparing sa'sages, wieners, and bolo nas, to 'extrude the sausage froma suita le machine lwhich is equipped with a tubular horn. Be-

fore beginning the extruding operation, the sausage-casing is gathered onto' the horn, and is allowed to slip therefrom as the extruding operation proceeds.

Where an artifical casing is to be'employed, there is great danger that the casing may be injured, particularly in the o eration of gathering the casing upon the orn. The primary object ofthe present invention is to provide an improved horn which will enable a casing to be athered thereon with facility, and without anger of injuring the casing. A further object is to enable the purpose just mentioned to be accomplished -in such manner that the subsequent extruding operation will not be impeded, but rather will be facilitated.

,The invention is illustrated in its preferred embodiment in the accompanying drawing, in which- Figure 1 represents brokenly, and partly in section, a stuffer-horn, constructed in accordance with the invention, the view illustrating the manner in which a sausage-casing is sli ped onto, or gathered, upon the` horn; an Fig. 2 represents a similar view, illustrating a modification of the invention.

Referring to Fig. 1, A represents a tubular hor'n equipped with an annular tip B; and C re resents the sausage-casing.

The tu ular member A may be formed by rolling a light strip of sheet metal into'tubular form and soldering the meeting edges; or the tube may constitute a seamless tube. The annular tip B may, be formed integrally with the tube A, in any suitable manner, or the tip may be separately formed, by-suitable turning operation, and may then be welded or solderedto the extremity of the tube' A. In either case, the tip is virtually formed' integrally with the tube, in the sense that it constitutes a rigid and permanent extension of the tube. The 'exterior surface 1 of the tip preferably constitutes a portion of a SphereA having a somewhat larger diameter-than the external diameter of the tube A. The tip has a relatively thick wall, whose inner surface is indicated at 2. Both' the innery and outer surfaces converge somewhat to the free extremity ofthe tp and coalesce with the rounded annular surface 3 ywhich forms an-annular lip encircling the Asomewhat contracted orifice 3* of the tip. In practice, the external diameter of the tip of the horn is slightly less lthan the diameter of the sausage-casing; and when the casing ;is applied to the' horn, it is gathered on the hornin a well understood manner. The' sausage is extruded from the sausage machine through the horn in a well-known manner. Usually the sausage machine is equpped with ascrew conveyor which 0perates'to radually extrude the sausage. As the extru ing operation proceeds, the operator regulates the' manner 'in which the sausage-casing slips from the horn; and, in this manner, the proper filling of the casing is regulated.

In a plying the sausage-casing to the horn, t e casng naturally tends to drop downwardly from the extremity of the horn. By employng the part-spherical surface at the tip, the free end portion of the tip presents a' rounded ta er which serves to gradually openthe casng. Moreover, this surface operates to so open the casing that it will not tend to catch on the edge presented by the extremity of the tip. Again, the annular extremity of the ti is so rounded that in case the upper wall o the sausage-casing should come in contact therewith, there is no danger of the casing catching and taal-ing..v

The tipl presents an external surface which s rounded in every direction; and the slight prominence of vthe tip facilitates thev drawin of the sausage-casing thereover and shrring or gathering the casing on the tube in the rear of said prominence. In the extruding operation, the operator is able tol easily regulate the withdrawal of the saus'age-casing by applying slight pressure upon the casing just back of -the largest diameter.

A In the modification shown in Fig. 2 A' represents asa-usage' machine horn, su ,al

' a socket into which the extremity of thetube vsa vto the horn.

is ordinarily employed in the art; and B' represents a removable tip applied thereto. Usually the extremity of the orn is cut on an incline, as indicated at 4. The tip B' may constitute a portion of a metal ball having the metal cut away at one side and a bore 5 formed in the metal, thus afording A' fits. The end wall 6 is provided with a perforation 6'. When the tp is applied to the tube, the air may escapethrough theI passage 6'; and if there be any of the meat pro'ecting, it may extrudef through fsaid' per oration. The casing C' may be slipped onto the horn after the tip B' has been applied to the horn. Obviously, the ltip B' afl:`ords a rounded vtaper extremity 'which serves to open u the casing as it is applied of 'the casing catching upon the. corner 4' of thetube. v

In employing4 the vconstructon shown in 'Fig. 2, the tip is removed after theV casing has been athered on "the horn and before the extru ng o eration begins. f

The improve device is es ecially 'desirable for use in connectionwit vsausage macasings made y from especially prepared cellulose hydrate.

and, while such casing possesses all the strength and tenacityV requisite for its purpose, thev artificial product will not slip reade tip prevents possibility Such artificial casings may' now be made with extremely thin walls;

ily onto a sausage-machine horn. The improved device enables the artificial casing to be applied to the horn with great facility, however; and, as indicated above, in the .preferredA form of invention' illustrated in .Figg 1, the 'improved device also facilitates the stufling operation.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permi'ssible,'in view of the prior art.

VWhat I regard as new, and desire to secure'by Letters Patent, is: v

1. A stufier-horn comprising a tube and a tip having an enlarged external diameter and presentng a rounded taper end surface.

2. A stufier-horn comprisng a tube and a thickened tip presenting a rounded annular end surface.

3. A stufer-horn comprising a, tube and anl annular ti inte ral therewith having relativelyV thic rounded annular lip.

4. A stufl'er-horn comprising a tube and, an annular tip' having a part-spherical exwa s terminating in a f ternal surface and having aninternal sur-* a removable part-spherical tip yhaving socket fitted on the end of said tube.V
